in the bracket 6 prevents nose, with such. accuracy as the location of the center of moiion Q or elastic cushions 25 as shown by Fig. 3. The gimbal consists-t a hoop 26 loosely surrounding the ring and-provided with two sets of pivots. One pivot passes 5 through the hoop and the ring at 27. and its mate passes through the same parts at a point diametrically opposite. At right angles to theseare the other pivots 28 passing through the hoop 26 and the standards It) 29, the last named being; formed as parts of the fixed hanger 23. The elastic cushions 25, when employed. are preferably made of rubber or of steel springs and are interposed between the head (3 and the fixed hanger 23. By u'ialcing' these cushions-of proper proportions and placing them suit- -'abl.y they may be caused to locate the center 0f motion where desired.

Having now described my invention, what 2'0 I claim as new, and. desire to secure by'Let tors Patent, isz' 1. In a centrifugal drive, the combination of a hanger, a sleeve member l1 aving a gyra tion bearing therein, a rotatable shatt ex tending through the sleeve member and adapted to carry a basket at the lower end, a motor rotor cured to the sha l t, a bearing adapted to withstand axial thrust and. located above the sleeve member and the motor 30 rotor, a niotor statrur. a bracket siu'iporting the motor stator and connecting: it with the sleeve member, and means to preyent the bracket from rotating.

In acei'itrltugal drive, the combination of a banner, a sleeve member having a gyra tion bearing; in the hanger. a motor stator. a bracket supporting thev motor stator. and connecting it with the sleeve uirai'iber. a motor rotor. a hearing adapted to withstand axial thrust and located atmre the sleeve member and the motor rotor, and a. shaft extending through the sleeve member. deriving support.- tronl the last named bearing,

and. adapted to carry a basin-2t at its lower 5 end. i

3. ln :1 cei'itri'tlunll drive, a bearing. a motor with its rotor below the been no]. a second bearing; below the rotor, and a spindle adapted for carrying a l'mr-ltet below the sa id bearings, rotating within them. and using each as a fulcrum in acting on the other to swing the frame of the n. tor about a point, between. the two.

4. In a. centrifugal drive, a l... earin e'. a motor with its rotor l'relow the bearing, a second bran-lug below the rotor. adapted "for can bearings, rotating within ilitfil. and |Slllfl each as a. fulcrum in acting on the other to tit) swiugr the frame oi the motor. and mean aspindle I mg a lHH-h'fll below the said 1 constraining the swinging to .take place about a pointbetween the bearings.

5. In a centrifugal drive, a hearing, the rotor of an electric motor below the bearing, a second bearing below the rotor, the frame of an electric motor connecting the'bca rings, a spindle rotating within the two bearings, acting and reacting laterally on both to swing the frame of the electric motor about a point bet-ween the two, and adapted for carrying a. basket below the bearings, and stationary means e'ngagingavith the stator of the motor to prevent its rotation.

6. In a centrifugal drive, a bearing, the rotor of an electric motor below the bearing, a second bearing below the rotor, the frame of an electric motor connecting the bearings, a spindle rotating within the two bearing; acting and reacting laterally on both to swing the frame of the electric motor, and adapted for carrying a basket below the bearings, means constraining the swinging to take place about a point between the bearings. and stationary means engaging with the stator ot' the motor to prevent its rotation.

'7. In a centritugal drive, two bearings swingable about a. point between them and forn'iing part of the stator of a motor, means for swingably supporting the stator, and a shaft rotatable in the two bearings and adapted to carry the rotor of the motor between the bearings and the basket of the centrifugal below them.

8. In a centriiugal drive,'-two' bearings constrained to swing about a point between them. and forming part'of the stator of a motor, means for swingably supporting the stator, and a shaft rotatable in the; two bearings and. adapted. to carry the rotor of the motor between the bearings and the basket of the centrifugal below them. I

f). In a centrifugal drive, the combination of a motor stator, means for swingably sup porting the same, a bracketforming part of the motor stator, a motor rotor below the bradcet, another bracketbelow the motor rotor and :torn'iing part of the motor stator, hearings held by the brackets, and a shaft affording support to the motor rotor, eontined hythe two bearings, deriving support from one of them, and adapted to carry a basketat its lower end.

In testimony. whereof I have signed. my

i name to this specification in the presence of.

two subscribing witnesses.
